Subject: [PATCH 0/2] mm: Fix N_CPU handlings of node_states
Date: Tue, 15 Oct 2013 11:12:54 -0600 [thread overview]
Message-ID: <1381857176-22999-1-git-send-email-toshi.kani@hp.com> (raw)
node_stats[N_CPU] tracks which nodes have CPUs on the system.
vmstat.c updates this N_CPU information, but it has multiple
issues.
Patch 1/2 changes setup_vmstat() to set up the N_CPU info at
boot. Patch 2/2 changes vmstat_cpuup_callback() to udpate
the N_CPU info at CPU offline.
